COLOSTOMY IRRIGATION APPARATUS Filed Aug. l5, 1958 2 Sheets-Sheet 2INVENToRs eofye/aoz This invention relates to improvements in colostomyirrigation apparatus, and more particularly to lmproved colostomyirrigating apparatus having valve means foicontrolling and stopping theflow of irrigating fluid through an associated catheter tube.

The primary object of the invention is to provide a simpler, moreeiicient and more practical apparatus of the character indicated whosevalve means enables the user of the apparatus to control at will, and toset beforehand, if desired, the ilow of irrigating fluid through thecatheter tube into the colostomy opening of the body, and to completelyshut off such ow, when desired, so that colostomy irrigations andevacuations are rendered substantially easier, more effective andcontrolled, more comfortable and sanitary, and accompanied by less odorand inconvenience.

Another object of the invention is to provide apparatus of the characterindicated above, whose manual valve means is incorporated in, or can beseparate and adapted to be mounted in the side wall of an ordinarycolostomy tube, opposite the upper, and usually ring-equipped receivingor intake end of the tube, the catheter tube being flexible andcompressible and being adapted to be passed through the valve means andthrough the intake end of the tube into the colostomy opening of thebody, the intake end of the tube being suitably secured in place on thebody, the valve means having a manually movable and adjustable memberwhich is adapted to be moved from an initial position in which thecatheter tube is wide open, to adjusted intermediate positions in whichthe catheter tube is pinched or compressed so as to controllably reducethe flow of irrigating fluid therethrough, and upon removal of thecatheter tube from the valve means, to a final position in which themovable member serves as a closure for the opening in the side wall ofthe colostomy tube so that spillage of fecal matter through such hole isprecluded when the colostomy tube is removed from the body after acolostomy irrigation.

A further object of the invention is to provide combined valve andadapter means of the character indicated above wherein the adjustableand movable member is slidably mounted on a relatively stationary memberwhich serves as mounting means for the valve means on the side wall of acolostomy tube, and as an adapter and support through which cathetertubes of differing diameters are passed, the arrangement of the movablemember and the stationary member being such that when the valve means ismounted in place on the side wall, manipulation of the movable memberrelative to the stationary member cuts the hole in the side Wall neededfor passage of the catheter tube.

Other important objects and advantageous features of the invention willbe apparent from the following description and the accompanyingdrawings, wherein, for purposes of illustration only, a specific form oftl e invention is set forth in detail.

Referring in detail to the drawings, wherein like or related numeralsdesignate like parts throughout the several views, and rst to Figures 1through l0, thereof, the apparatus illustrated therein, and generallydesignated 20, comprises a conventional form of flexible transparentcolostomy tube 22, having an intake or receiving opening 24 at its upperend having a peripheral edge portion 26 securably engaged around theannular flange 28 and between the flange 28 and a divergent annularflange 30 of a usually metal ring 32, to which related ends of bodyencircling straps or belts 34 and 36 are suitably secured, for holdingthe ring 32 against the body, around its colostomy opening (not shown)preparatory to and during a colostomy irrigation and evacuation. Thecolostomy tube 22 has a side wall 38, and a portion lll thereof,opposite the ring 32 when the tube 22 is in place on the body, as shownin Figure l, mounts a combined valve and adapter 42.

The combined valve and adapted 42, comprises a relatively stationarymember, in the form of an adapter 44, which comprises an inner section46 and an outer section 4S. The inner section 46 comprises a tubularcylindrical main portion Sd having on its longitudinally inward end alateral annular hook ange 52 which defines an annular groove 54 aroundthe outward side of the main portion S0 which faces toward thelongitudinally outward end of the inner section 46. The outward side ofthe main portion 5t) is circumferentially indented near thelongitudinally outward end 56 of the inner section 46, to define anannular groove S3 which is spaced longitudinally from the groove 54.

The outer section 48 of the adapter`44 comprises a relatively flatannular side wall 60 which is larger in diameter than the L-shapedflange 52 of the inner adapter section 46, a lateral annular flange 62projecting inwardly from the outer end of the side wall 60, and anannular longitudinally inwardly projecting flange 64 on the inward edgeof the flange 62. The flange 64 has a terminal free edge`66 which isspaced longitudinally outwardly from the free edge 68 of the side wall60. The inside diameter of the annular flange 64 is such that theannular flange 64 can slidably and freely telescope onto the cylindricalmain portion 50 of the inner adapter section 46, as shown in Figures 6,7 and 8. v

When the outer adapter section 48 is thus telescoped into and assembledwith the inner adapter section 46, the flange 64 of the outer section 48engages loosely in the groove 54 of the inner section 46, and the flange70 of the hook flange 52 engages loosely in the'groove 72 defined by theside wall 60 and the flange 64 of the outer adapter section 48; and theouter end of the main portion 50 of the inner adapter section 46, andthe circumferential groove 58 are exposed beyond the outer end of theouter adapter section 48, as is apparent in Figures 6, 7, and 8.

In order to apply the adapter to the sidewall portion v40 of thecolostomy tube 22, the sections 46 and 48 are separated and then engagedwith the inward and outward sides of the tube side wall portion 40,respectively, and are then pushed together into telescoped relation, soas to clamp and wedge portions of the side wall portion 40 in thegrooves 58 and 72, as shown in Figures 6, 7 and 8. The outer section 48is then rotated relative to the inner section 46, while the innersection is held stationary, so

as to sever the material of the tube side wall portion and form anopening 74 therein having annular free edge 76 in the region of thegroove 58, the cut away material being then removed to expose the outerend of the inner section 46 and is disposed of.

The combined valve and adapter 42 further comprises a valve slide,generally designated 80, which is installed on the exposed outer end ofthe inner adapter section 46 following the above described applicationof the adapter 44 to the bag 22.

The valve slide 80 is elongated transversely of the adapter 44 andcomprises a flat elongated plate portion 82, about three times greaterin length than the diameter of the outer end 56 of the inner adaptersection 46, and having an arcuate end 84, and along the oppositelongitudinal side edges of the plate portion 82, and projectinglaterally inwardly therefrom at and beyond the inner side 86 of theplate portion 82 is a continuous hook flange 88 having a laterallyprojecting flange 90 which is spaced from the inward side 86 of theplate portion 82 and has a free laterally inward edge 92, and free endedges 94. -The hook flange 88 does not extend along the squared end 8Sof the plate portion 82, so that entrance is provided at this end of theslide 80 to enable the slideV 80 to be operatively engaged on theexposed outer end 56 of the inner adapter section 46, with the free edge92 of the hook flange 90 engaged slidably and rotatably in thecircumferential groove 58 of the inner adapter section 46.

The inner side 86 of the plate portion 82 of the slide 80 is providednear its arcuate end 84 with a cylindrical boss 96 of a diameter to actas a closure for the outer end of the bore 98 through the main portionS0 of the inner adapter section 46, as shown in Figure 8, when the slide80 is moved endwise relative to the adapter 44 so as to place the boss96 in frictional engagement with and in registry with the outer end 56of the inner adapter section 46. In other positions of the slide 80 theinner side 86 of the plate portion 82 is not so frictionally engagedwith the outer end 56 of the adapter section 46.

As shown in Figures 7, 8 and 9, the plate portion 82 of the slide 80 isprovided near its squared end 85 with a circular catheter tube passingopening 100 of a relatively large diameter, and at a point between andspaced from the opening 100 and the boss 96, with a circular catheterpassing opening 102 of a diameter smaller than that of the opening 100,the purpose being to selectively and snugly accommodate catheter tubesof different diameters.

As shown in Figures 1 and 5, the above described assembly of componentshaving been achieved, the particular flexible and compressible cathetertube 104 is passed inwardly through such as the smaller hole 102 of theslide 80, through the bore 98 of the inner adapter sec tion 46, acrossthe tube 22, through the tube ring 32, and into the colostomy opening inthe users body, not shown, whereat the irrigating fluid, such asprepared water in a suitable container (not shown) is run through thecatheter tube 104 and into the colostomy body opening through thecatheter tube nozzle 106 for producing the desired irrigation andevacuation.

Where full flow of irrigating fluid is not desired or it is desired tovary the rate of flow of fluid during the process, the slide is movedendwise from the position shown in Figures 5 and 8, to an intermediateposition, wherein one side of the edge of the slide opening or hole 102is brought nearer to the opposed side of the bore 98 of the inneradapter section 46, so that the catheter tube 104 is compressedtherebetween and its bore thereby re duced in cross section so as toreduce the flow of fluid through the catheter tube 104; and if desired,to completely cut off such flow, in such a way as to hold the injectedfluid in the intestine of the user of the device `for a desired periodof time.

When it is desired to effect an evacuation, the catheter tube 104 iswithdrawn from the body opening so as to enable flow of fecal matter andirrigating fluid into the tube 22 through its intake opening 24. Afteran evacuation, the catheter tube 104 can be withdrawn also from theadapter 44, and the slide 80 moved endwise to the closure effectingposition shown in Figure 8, wherein the boss 96 closes the bore 98through the inner adapter section 46 and prevents any escape of fecalmatter and accompanying odor from the tube 22 through the side wallopening 74, and only through the open lower end of the tube 22, whichwill usually be located in a disposal container, such as a toilet bowl.The closed position of the slide 80 is maintained until after the devicehas been removed from the body of the user, to enable emptying the tube22 without danger of leakage through the side wall opening 74. If thetube 22 is to be disposed of after usage, the adapter 44 is removed byseparating its sections 46 and 48 before throwing the tube away, forVreuse on a fresh tube.

The form of combined valve and adapter shown in Figures 11 and 12, andgenerally designated 42a, differs from that shown in Figures l to l0 anddescribed above, in that the plate portion 82a of the slide 80a has onlyone catheter tube passing hole 100a, located at its squared end a, and atapering catheter tube compressing and wedging slot 110 is providedlongitudinally of the plate portion 82a between the boss 96a and thehole 10011, and has its wider end opening diametrically into the hole a,as indicated at 112, for compressing a catheter tube as the slide 80a ismoved endwise relative to the catheter tube and the adapter 44a in thedirection of the catheter tube originally passed through the hole 100a.

The combined Valve and adapter 42a differs further from that of Figuresl to 10, only in that the grooves 54a and the flanges 70a and 64a of thesections 46a and 48 are Asomewhat shallower than the correspondingcomponents of Figures 1 to 10, and are rounded or transversely curvedand effect less damaging but equally secured engagements with the sidewall portion 40 of the side wall 38 of a colostomy tube 22.
